I am in the Steel of Heart

Traveled to a seemingly peaceful but actually turbulent world of stitched monsters.Gong Yangzhen, who had no relatives but could barely make ends meet by working, thought he would live a dull life.It wasn't until he discovered that this world seemed to have an unwritten rule that the distribution of benefits was determined by an underground fighting competition called Kengan that he felt something was wrong.Then the situation escalated further -The LOL Fighting Spirit Arena that I was playing before traveling through time seemed to have traveled with me?Zaun Madman Mundo template?Hextech enhancement runes?I'm so, I steeled your heart?!This book is also known as "Steel Door", "A lot of meat and outrageous damage", "Who said meat can't kill people?"PS: It is expected that the world will be stitched together with "Kengan Ashura", "Sweat! Fitness Girl", "One Victory, a Thousand Gold", "Five Equal Divisions", etc.
